The basic steps of this method are as follows.The firststep is to derive a necessary condition such that the families of quasipolynomials withone parameter,corresponding to the edges of the polytope,have pure imaginary rootsby using the Dixon's resultant for polynomials.Then to check that the casescorresponding to the parameters obtained in the first step are in fact impossible byusing the generalized Sturm criterion and some stability criteria.

其基本思路是先利用多项式方程组的Dixon结式理论导出使各棱边对应的单参数特征拟多项式有纯虚根时，参数值应满足的一个等式条件，即所谓的Dixon结式等于零，然后由广义Sturm判别法验证对所有参数值，Dixon结式不等于零，或使结式等于零的解不产生特征拟多项式的纯虚根。

May 3. I began with my Saw, and cut a Piece of a Beam thro', which I thought held some of the upper Part or Quarter-Deck together, and when I had cut it thro', I clear'd away the Sand as well as I could from the Side which lay highest; but the Tide coming' in, I was oblig'd to give over for that Time.

五月三日我动手用锯子锯断了一根船梁。我猜想，这根船梁是支撑上面的甲板或后面的甲板的。船梁锯断后，我尽力清除旁边积得很高的泥沙。但不久潮水开始上涨，我不得不暂时放弃这一工作。
